The detection member 30 is threadedly connected to the connection seat 20, and one end of the detection member 30 is disposed in the flow channel 11 through the threaded hole 25. The detection member 30 is used to detect the pressure, flow rate and temperature data of the fluid in the flow channel 11, and transmit the data to the control system of the fuel cell engine. Among them, the outer wall of the insertion portion 21 is provided with a block 211, and the inner wall of the connector 15 is provided with a slot 17.

[0044] Furthermore, a limiting groove 212 is provided on the clamping block 211. The limiting groove 212 is provided at one end of the clamping block 211 away from the insertion portion 21, and the limiting groove 212 is in the shape of a groove.

The receiving groove 221 is arranged in an annular groove structure, and a first rubber ring 222 is arranged in the receiving groove 221. The first rubber ring 222 is arranged in an annular shape, and one side of the first rubber ring 222 is embedded in the receiving groove 221, and the other end of the first rubber ring 222 abuts against the detection member 30 to seal the joint position between the detection member 30 and the connection seat 20.
[0046] Furthermore, the detection member 30 is a temperature and pressure sensor, and an external thread is provided on the outer side of the detection member 30 to ensure that the detection member 30 is threadedly connected to the connecting seat 20 through the threaded hole 25, and the end of the detection member 30 penetrates through the threaded hole 25 into the flow channel 11 to detect the data information of the fluid in the flow channel 11. In this embodiment, an embedding groove 31 is provided on the detection member 30, and the embedding groove 31 is an annular groove shape and is arranged around the outer side of the detection member 30. A second rubber ring 32 is provided in the embedding groove 31, and the second rubber ring 32 is abutted against the connecting seat 20. The second rubber ring 32 is pressed against the end of the threaded hole 25 to improve the airtightness of the joint position between the detection member 30 and the connecting seat 20.
[0047] Furthermore, the first rubber ring 222 and the second rubber ring 32 are both annular, the central axis of the first rubber ring 222 is colinear with the central axis of the second rubber ring 32, and the first rubber ring 222 is arranged around the outer side of the second rubber ring 32, so as to form a double-layer sealing structure, thereby improving the airtightness between the detection member 30 and the connection seat 20. In the present embodiment, a top pressure surface 26 is provided at one end of the threaded hole 25 close to the detection member 30. The top pressure surface 26 is inclined and gradually diffused from the insertion portion 21 to the positioning portion 22, and the second rubber ring 32 is pressed against the top pressure surface 26. By tilting the top pressure surface 26, the detection member 30 is threadedly connected with the connection seat 20. As the depth of the detection member 30 inserted into the threaded hole 25 increases, the pressure applied by the top pressure surface 26 on the second rubber ring 32 will gradually increase, further improving the airtightness at the joint position of the detection member 30 and the connection seat 20.
